So I have this new business idea and need some feedback

It's an interesting idea. I guess the problem I'd see with it is just that the market for it would be pretty small. There are billion HS dances/parties/etc., but there are only going to be a handful of people who would be looking for a DJ in that target market. As long as you don't have to put in a lot of work for it otherwise, you might as well give it a go. But if you have to buy a bunch of equipment, I'd be wary until you quantify the true market for it.

That said, I'm 27, so I may not be an expert on that market.
